Data Link Layer
Network and Transport Layer
Part of the OSI MODEL
Bottom Layers (1 -2 ) - Transmit Data Packets
Middle Layers (3-5) - Communication Layers
Top Layers (6-7) - Presents Data to Users
Note the difference between Analogue, Digital and Fiber Optic Signals. Basic Network Anatomy: 1. Network Hardware -router, switches, hubs, gateways, access points, network interface cards, cables, bridges, modem, Integrated Services Digital Network (ISDN) and firewalls
Enables the users to share computer hardware resources, reducing cost and making it possible for more people to take better advantage of powerful computer equipment.
2. Network Software
Enable users to share data and software programs, increasing efficiency and productivity.
3. People
Network enable people to work, play, communicate in ways that otherwise difficult or impossible.
We will be discussing the IT CONCEPTS OF NETWORKING. Some topics were assigned; you will see the names right beside the topics.
1.Client, host, server (See Basic P2P)
Computer systems which are used as central location of data and programs. Commonly shared by different users in a network environment.
2. Mainframe, supercomputers
3. Grid Computing and Distributed processing [SANG]

4. Ethernet, peer to peer
Ethernet - uses a communication concept called datagrams to transfer messages across the network. Datagrams take the form of self-contained packets of information comprising fields that contain information about their data, origin, destination and type. The data field in each packet can contain up to 1500 bytes. Take mailing as a . An Ethernet packet is not just a letter. It also contains the sender address, receiver address and the stamp indicating the exact contents of that packet.("DeviceNet vs Ethernet."

Things you must know about Ethernet
Peer to peer - is different from traditional file downloading. In peer-to-peer sharing, you use a software program (rather than your Web browser) to locate computers that have the file you want. Because these are ordinary computers like yours, as opposed to servers, they are called peers. The process works like this:
You run peer-to-peer file-sharing software (for example, a Gnutella program) on your computer and send out a request for the file you want to download.
To locate the file, the software queries other computers that are connected to the Internet and running the file-sharing software.
When the software finds a computer that has the file you want on its hard drive, the download begins.
Others using the file-sharing software can obtain files they want from your computer's hard drive.
The file-transfer load is distributed between the computers exchanging files, but file searches and transfers from your computer to others can cause bottlenecks. Some people download files and immediately disconnect without allowing others to obtain files from their system, which is called leeching. This limits the number of computers the software can search for the requested file.
